Features and Benefits
MAJOR BENEFITS OF THERMAL MASS FLOW METERS
■
Direct Mass Flow – No need for separate temperature or pressure
transmitters
■
High Accuracy and Repeatability – Precision measurement and
extraordinary repeatability
■
Turndown of 100 to 1 and resolution as much as 1000 to 1
■
Low-End Sensitivity – Measures as low as 5 SFPM (e.g., 1 SCFM
in a 6" pipe)
■
Negligible Pressure Drop – Will not impede the flow or waste energy
■
No Moving Parts – Eliminates costly bearing replacements, and
prevents undetected accuracy shifts
■
Dirt Insensitive – Provides sustained performance
■
Low cost-of-ownership
■
Ease of installation and convenient mounting hardware
SPECIFIC BENEFITS OF THE SAGE RIO
n
Features In-Situ “Field Zero Calibration Check” of sensor’s perform-
ance – verifies that the sensor is clean, and assures that there is no
drift, or shift in the flow meter
n ATEX Zone 1 Approval with T6 Rating suitable for gases with ignition
temperature as low as 185°F (85°C). Also UL, CSA and CE approved
n High contrast photo-emissive OLED display with numerical Flow
Rate, Total and Temperature, as well as Graphical Flow Indicator
n Calibration milliwatts (mw) is continuously displayed, providing for
ongoing diagnostics
n Photocell activated Screen Saver to extend display life
2
n Proprietary hybrid-digital sensor drive circuit provides enhanced
signal stability and temperature compensation
n Modbus® compliant RS485 RTU communications (HART® optional)
1
n Isolated 4-20 mA
3
output and pulsed output of Totalized Flow
n Heavy industrial packaging with easy terminal access
n
Optional Remote Style with Lead-Length Compensation. Allows remote
electronics up to 1000 feet from probe; Explosion Proof Junction Box
has no circuitry, just terminals (suitable for harsh environments)
n Low power dissipation, under 2.5 Watts (e.g. under 100 ma at 24 VDC)
n Field reconfigurability via optional Addresser software
n Flow conditioning built into In-Line flow meters (1/2" and up)
n Captive Flow Conditioners for Insertion meter applications, if required
SAGE RIO THERMAL MASS FLOW METER FOR GASES
The Sage Rio Thermal Mass Flow Meter provides the same levels of
performance found in the popular Sage Prime with the added ATEX
Zone 1 Flame proof approvals. The Rio features a bright, high con-
trast, photo-emissive OLED (Organic LED) display of Flow Rate, Total
and Temperature in an explosion proof, dual-sided IP66 (NEMA 4X)
enclosure. The Flow Rate is also displayed graphically in a horizontal
bar graph format. The rear compartment is completely separated
from the electronics, and has large, easy-to-access, well marked
terminals, for ease of customer wiring. It is powered by 24 VDC
(115/230 VAC optional). The power dissipation is under 2.5 watts
(e.g. under 100 mA at 24 VDC).
Standard outputs include 4-20 mA with HART communication
1
,
pulsed outputs of totalized flow and full Modbus compliant RS485
communication.
Sage Rio is Zone 1 approved: II 2G Ex d IIB+H2 T6 Gb.
T6 Rating is suitable for gases with ignition temperature as low as
185°F (85°C).
CONTINUOUS DIAGNOSTICS & FIELD CONFIGURABILITY
Rio has continuous diagnostics. The raw calibration milliwatts (mw)
is always displayed in the upper left hand corner of the meter’s dis-
play. At any time, you can check this reading at a “No Flow” (0 SCFM)
con dition, and compare the reading to the original re ported “No
Flow” value noted on the last few lines of your meter’s Certi ficate
of Con formance or the Flow Meter’s data tag. This in-situ diagnostic
procedure not only checks the sensor performance and the “Live
Zero” calibration point, but it also verifies that the sensor is clean.
It essentially provides a means to validate that the meter is oper -
ating properly, verifies that there is no shift or drift, and eliminates
the need for annual fac tory calibrations. This simple field diag nostic
procedure, in addition, verifies that the sensor is free from contami -
nation, even without inspection.
Although Sage Rio is fully configured upon shipment for the pipe
and process con ditions requested, if changes are needed, HART or
Addresser software is optionally available.
1 Specify HART in the Flow Meter part number
2 Note, a built-in photocell continuously monitors the ambient light, and adjusts the display brightness for
optimum long-term life, and also senses motion which automatically switches display from Screen Saver
mode to Normal mode
3 In optional HART enabled flow meter, the 4–20 mA MUST be externally powered. In the standard models,
a jumper provides the option to either power the 4–20 mA from the flow meter or to externally power
(loop power) the 4–20 mA
